According to an embodiment, at least a portion of the case 130 may be formed of a metallic material. The entire case 130 may be formed of a metallic material, the entire periphery of the case 130, which is exposed to the outside between the front surface 110 and the rear surface 120, may be formed of a metallic material, or at least a portion of a surface of the case, which is exposed to the outside, may be formed of a metallic material. At least one segmentation part 140 (or an insulation layer (an insulation member and a bonding layer)) may be partially arranged at a periphery of the case 130. Depending on arrangement of the at least one segmentation part 140, the case 130 may include a body part that has a main body and one or more auxiliary bodies 131, 132, 133, 134, 135, and 136. At least some of the main body and the auxiliary bodies 131, 132, 133, 134, 135, and 136 may be formed of a metallic material. The main body and the auxiliary bodies 131, 132, 133, 134, 135, and 136 may be electrically or physically separated by the segmentation part 140.

The SIM insertion part 160, for example, may have a shape that is stepped from the first side surface 130a, and may have a shape of a through-hole that extends inwards. For example, a bonding layer and an insulation member having specific thicknesses may be formed (or disposed) on an inner surface of the SIM insertion part 160 such that the inserted SIM and the SIM insertion part 160 at least a portion of which is formed of a metallic material are electrically insulated from each other. According to various embodiments of the present disclosure, the fourth side surface 130d, for example, may include an ear jack 170 and a USB connector 180. The bonding layer and the insulation member, which have been described above, may be formed around the ear jack 170 and the USB connector 180 to have specific thicknesses.

Meanwhile, various embodiments are not limited to the above-described structure. For example, the electronic device 100 may include segmentation parts, the number of which is larger or smaller than that of the above-mentioned segmentation parts. Accordingly, some of the above-mentioned auxiliary bodies may be electrically connected to the main body and may be integrally formed. Accordingly, it may be understood that the auxiliary body described in various embodiments may include at least one segmentation part to be electrically separated from the main body and at least one segmentation part may be arranged in the electronic device. Hereinafter, an arrangement relationship between an auxiliary body and a main body (or between an auxiliary body and another auxiliary body) will be described with reference to the first auxiliary body 131 and the main body that are arranged on the first surface 130a.

FIG. 2 is a view illustrating a case according to an embodiment of the present disclosure.

FIG. 5 is a flow chart that illustrates a method for manufacturing a case according to an embodiment of the present disclosure. FIG. 6 is a view illustrating a shape of a case in a case manufacturing process according to an embodiment of the present disclosure.

Referring to FIGS. 5 and 6 , the method for manufacturing a case, for example, may include a preform preparing operation 501, an adhesive coating operation 503, an insert injection-molding operation 505, a bonding layer washing and removing operation 507, and a final machining and surface-processing operation 509. The bonding layer washing and removing operation 507 may be omitted depending on a condition of the manufacturing process. Further, the bonding layer washing and removing operation may be included in the surface-processing operation 509.

The preform preparing operation 501, for example, may be an operation of preparing a preform that will be utilized as a case of an electronic device 100. In the preform preparing operation 501, a preform, at least a portion of which is metallic, may be provided. The preform preparing operation 501, for example, may include a process of machining a metal that will be used as a case. The metal machining process may be a process of machining a mold into a specific form by inserting a metallic preform into an injection-molding mold of a specific size, and may include a processing operation of forming a space into which an insulation member (for example, the insulation member 343) (for example, a polymer resin) may be inserted. The preform preparing operation 501 may include at least one process of casting, rolling, extrusion, forging, full CNC, pressing, or a combination thereof.

The preform preparing operation 501, for example, may include a machining process of forming an auxiliary body (for example, the auxiliary bodies 131, 231, 331, and 431) (for example, an antenna) and a main body (for example, the main bodies 239, 339, and 439) such that the surface roughness of the auxiliary body and the surface roughness of the main body are Ra (average roughness) 0.001 to 1.5 μm or Rz (maximum roughness) 0.005 to 5 μm. Further, the preform preparing operation 501 may include a machining process of differently forming the roughness of the auxiliary body and the roughness of the main body depending on the locations of the facing surfaces of the auxiliary body and the main body. For example, the preform preparing operation 501 may include a metal machining process of making the roughness of an area that is covered by a front surface (for example, the front surface 110) larger than the roughness of an area exposed to the outside, in the facing surfaces of the auxiliary body and the main body. Through this, various embodiments may improve a support strength by increasing an area in which a bonding layer and an insulation member are arranged in areas (having large Ra and Rz values) having relatively rough surfaces, and may couple the bonding layer and the insulation member to the auxiliary body or the main body firmer to show waterproof, dustproof, and insulation effects in areas (having small Ra or Rz values) having relatively uniform surfaces.

The adhesive coating operation 503 may include a pre-processing process for removing metallic impurities, oil stains, and cutting oil that are stuck to a coating target (for example, the facing surfaces of the auxiliary body and the main body and an area of the main body). The pre-processing process, for example, may include a process of removing impurities on a surface of the coating target by complexly using a surfactant degreasing solution, an alkali degreasing solution, an acid degreasing solution, or the like. According to an embodiment, in the case of aluminum, the pre-processing process may include a surfactant processing process, an alkali processing process, and an acid processing process. The adhesive coating operation 503 may include a process of electro-depositing a material for a bonding layer while an electric current (0.5 to 5 A/dm2) to a surface of the coating target. The material used for the bonding layer, for example, may include an organic bonding material. The organic bonding layer material may be triazine thiol, dibuty amino, dithio pirymidine, or a silane-based composition, and a thickness of the coating layer may be 0.1 to 3 m.

Further, the bonding layer may be attached to various electrified surfaces so that it may be formed even after the coating target is plated or an anodizing layer that is thin enough to be electrified is formed. Accordingly, the adhesive coating operation 503 may include a surface processing process such as plating or anodizing according to a purpose of the coating. Further, the adhesive coating operation 503 may include a process of forming an anodizing layer and a bonding layer at the same time. For example, the adhesive coating operation 503 may include a process of forming an anodizing oxidation layer and a complex substance film of an adhesive at the same time.

The insert injection-molding operation 505 may include a process of inserting a polymer resin into a bonding layer area on which the adhesive is coated. Through this, the insert injection-molding operation 505 may be a process of electrically separating an antenna part (for example, the auxiliary body) and other metallic housing (for example, the main body) from the case. The antenna part may be utilized as an antenna of a specific communication module of an electronic device or an auxiliary antenna of a specific communication module to improve the efficiency of the antenna. During the insert injection-molding operation 505, the temperature of the mold and the temperature of an insert material (for example, the polymer resin) may be maintained at 130 C or more such that the polymer resin (for example, the insulation member) and the bonding layer substance sufficiently react with each other. The thickness of the insulation member layer 343, for example, may be 0.5 to 2.5 mm. The insulation member may be poly phenylene sulfide (PPS), poly butylene terephthalate (PBT), polyimide (PI), or polycarbonate (PC), and may include inorganic particles (ceramic, glass fibers, or the like) that are suitable for reinforcing mechanical properties. According to an embodiment of the present disclosure, the insulation member may be a resin a fluidity index of which is 24 to 30 g/10 min.

The bonding layer washing and removing operation 507 may be applied or omitted according to occasions or a process environment. The bonding layer washing and removing operation 507 may include a process of removing an adhesive layer (or a bonding layer attached to the outside of a metal) that does not react to be left in the adhesive coating operation. In this process, the bonding layer washing and removing operation 507 may include a flushing process of washing the bonding layer with water. The temperature of water in the flushing process may be about 40 to 60° C. The bonding layer washing and removing operation 507 may include a process of removing water left on a surface of a target object after the flushing process by using an air gun or an air shower facility. Further, the bonding layer washing and removing step 507 may include a process of drying moisture to completely remove the moisture. The drying temperature may be about 60 to 100° C. The bonding layer washing and removing operation 507 may be a process of ensuring electrical connection of an electrically connected part of the electronic device and attachment forces of components during surface processing and removing stain errors, and may be selectively managed.

According to various embodiments of the present disclosure, the bonding layer washing and removing operation 507 may include an alkali cleaning process and an acid cleaning process. In the case of an aluminum material, the bonding layer washing and removing operation 507 may be performed during an anodizing pre-processing process.

The final machining and surface-processing operation 509 may be a process that is performed after the process of removing the bonding layer, and may be an operation in which manufacturing of the case is finished. The final processing and surface-processing operation 509, for example, may include a metal machining operation or an injection-molding operation. As illustrated in operation 509 of FIG. 6 , only an area that will be used as the case of the electronic device is left through a periphery machining operation and a battery area machining operation.

The aluminum metal member may be an Al—Mg alloy, an Al—Zn—Mg alloy, or an arbitrary aluminum alloy as well as pure aluminum. The above-mentioned polymer resin, for example, may include a thermoplastic resin. The thermoplastic resin may include polyethylene, polypropylene, polyvinyl chloride, polyvinyl acetate, polyacrylate ester, polymetaacrylate ester, unsaturated polyester, polyester, polyamide, polyether, polyurethane elastomer, polystyrene, polyarylsulfone, polyarylate, polyacetal, polyethylene terephthalate, polycarbonate, polyphenylene ether, polyphenylene Bauxite, polyphenylene sulfides, polybutadiene, polybutylene terephthalate, polymetalpanel, and a liquid crystal polymer alloy. Further, the thermoplastic resin may contain a glass filler, a carbon filler, metal whisker, calcium carbonate, a filer or a pigment and a stabilizer.

The network 1262 allows contents stored in the electronic device 1201 to be transmitted to the first external electronic device 1202, the second external electronic device 1204, or the server 1206. The server 1206 may form a communication channel with the electronic device 1201 through the network 1262. The server 1206 may receive contents from the electronic device 1201 and store the received contents. Further, the server 1206 may provide a feedback for the reception of the contents to the electronic device 1201.

The display 1260 may include a touch screen, and may receive, for example, touch, gesture, proximity, or a hovering input using an electronic pen or part of a body of the user.

The communication interface 1270 may establish communication between, for example, the electronic device 1201 and an external device (e.g., a first external electronic device 1202, a second external electronic device 1204, or a server 1206). For example, the communication interface 1270 may connect to a network 1262 through wireless communication or wired communication and may communicate with the external device (e.g., the second external electronic device 1204 or the server 1206).
